Highly sound insulating hollow clay tile for the construction of floors

Abstract

A highly sound insulating clay tile for the construction of floors has an outer substantially parallelepiped shape with symmetrical, laterally projecting portions for the support of each tile by reinforced concrete floor beams. Each tile comprises a peripheral wall having a substantially uniform thickness. Extending from this peripheral wall toward the inside of the tile are a plurality of very short vertical and horizontal partitions. The plurality of horizontal and vertical partitions are combined with other horizontal and obliquely inclined partitions for defining two main longitudinal cavities having a polygonal or circular cross section. The main cavities are symmetrically positioned with respect to a vertical center plane, and the cross-sectional area of the main cavities comprises a major portion of the cross-sectional area of each tile.

What is claimed is: 
     
       1. A highly sound insulating hollow clay tile for the construction of floors, the tile having a parallelepiped outer shape of a substantially rectangular cross section with lateral symmetrically projection portions (1,6) for the connection of each tile with the adjacent carrying beams of a floor made of reinforced concrete, said tile further having a peripheral wall (3) of a substantially uniform thickness, said peripheral wall (3) comprising upper and lower horizontal wall elements from which extend towards the inside of the tile a plurality of very short vertical partition walls (3v) and vertical wall elements from which extend towards the inside of the tile a plurality of horizontal partition walls (3c) of very short length, which cooperate to define therebetween a plurality of small sound insulating polygonal cavities (4) of different form and dimension, and, which in combination with other inner inclined longitudinal partitions (3a) and with other horizontal partitions (3u), defined two large main longitudinal cavities (2), symmetric with respect of a longitudinal vertical center plane (x--x) of each tile, said main cavities (2) occupying the most part of the cross section of the tile, and being thus entirely separated from one another, as well as from the outside by a series of the small sound insulating cavities (4). 
     
     
       2. A tile according to claim 1, wherein the cross section of each main cavity (2) is circular so that the partitions (3i) encircling each cavity are shaped as archs of a same circumference. 
     
     
       3. A tile according to claim 1, wherein with reference to a constant transversal width of the tile, the hollow tiles have greater or smaller heights according to the thickness of the floor, the height of the the main cavities (2) increasing as the tile height increases and respectively decreasing as the height of the tile decreases, so that the main cavities (2) will have accordingly a vertically elongated or shortened cross section. 
     
     
       4. A sound insulating hollow clay tile for the construction of floors comprising: a generally straight peripheral wall having a uniform thickness and forming a parallelepiped outer shape of a substantially rectangular cross section, the wall having straight portions (1,6) laterally projecting at discrete angles from the wall for forming a hollow shoulder for the connection of each tile with an adjacent carrying beam of the floor;   a plurality of short, straight vertical partitions (3v) extending from horizontal portions of the peripheral wall and toward the inside of the tile;   a plurality of short, straight horizontal partitions (3o) extending from vertical portions of the peripheral wall and toward the inside of the tile;   a plurality of straight inclined partitions (3i) connected to the horizontal and vertical partitions for forming first and second polygonal main cavities symmetric with respect to a longitudinal center plane (x--x) of each tile and for forming a plurality of smaller cavities completely surrounding each main cavity, each vertical, horizontal, or inclined partition wall being connected to an adjacent vertical, horizontal, or inclined partition wall at a discrete angle.   
     
     
       5. The tile according to claim 4 further comprising a horizontal inner partition (3u) disposed between the first and second main cavities and connected at a discrete angle to an inclined partition of each main cavity.
